SQLite

SQLITE3.0 uses the C function interface, which is commonly used as follows:Sqlite3_open ()//Open DatabaseSqlite3_close ()//Close DatabaseSqlite3_exec ()//Execute SQL statements, such as creating tablesSQLITE3_PREPARE_V2 ()//Compile SQL

Recently engaged in SQLite local query, the requirement is to query the data for a time period, in SQL we know that:[SQL]View Plaincopyprint? SELECT * from tblname where rdate between ' 2008-6-10 ' and ' 2008-6-12 ' /c3> SELECT *

Zeng: All programming is data-centric, and I think it makes sense.The so-called database database, no data called what database, then see how to insert data in the table.One insert data1 Creating a TableFirst, to insert data, you need to create a

Objective:General database query strings are ignored and case-insensitive, but SQLite queries are case-sensitive. However, SQLite supports ignoring case when defining tables/queries.Add collate when defining database table/query matching nocaseSuch

Use steps1. Introduce the header file: Add the frameworks and libraries that will be used under the project Build phases. I've added the sqlite3 I'm going to use in the project.2. Specify the database storage path: The database is generally stored

Once the database is created, we may want to see if the data in the database was successfully inserted, and many people prefer to use the graphical interface tools to manage the SQLite database. SQLite GUI management tool has many, I recommend using

Before doing so much not just for the data to get a few tables, then see how to create a new table.A new tableThe basic syntax is as follows:CREATE TABLE database_name.table_name ( column1 datatype PRIMARY KEY (one or more columns), column2

The syntax of SQLite differs from that of SQL Server. For example, to insert data, the field indicating the seed must be specified as null to obtain a new ID. Code highlighting produced by Actipro CodeHighlighter

If the database in an application does not require external access, implement a Database Help class inherited from SQLiteOpenHelper to support database creation and version update, which cannot be implemented by SQLiteDataBase. however,
